[3] Movement speed during OP shift
When using the OP shift function, the movement speed during the OP shift is set
in "
Pr.56
Speed designation during OP shift
". The movement speed during the OP
shift is selected from either the "
Pr.46
OPR speed
" or the "
Pr.47
Creep speed
". For
the acceleration/deceleration time, the value specified in "
Pr.51
OPR
acceleration time selection
" or "
Pr.52
OPR deceleration time selection
" is used.
The following drawings show the movement speed during the OP shift when a
mechanical OPR is carried out by the near-point dog method.
